Transferring data from – doesn't load ads/JS?

When I access my website (http://www.cvplaza.com) using Firefox with W3 Total Cache enabled, many of my pages show “Transferring data from…” and don’t load a number of the ads. This problem, however, disappears when I disable the plugin. Also, when I click away from the page that was loading, all the ads appear before the page redirects to its new location.
